Application filed. August 31, 1923. Serial i NlO. 566 459;

To .aZZ whom it may concern: M

Be it knownthat I, JAMES ALBERT HOGG, a citizen of the United States, residing" at Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Bacl: lVasher Immersing and Squeezing Feede-r, of which the following is a specification. f

This invention relates to an immersing and squeezing mechanism for back washers for card and comb tops, etc., and similar machines for immersing the stock, s ueezing it and supporting it while feeding.

The principal object of the invention is to provide a simplified means for supporting the top rolls and permitting of taking them all out of the Washer collectively and conveniently instead of individually as hereto fore, thus greatly simplifying" the operation of passing the material through as welLas re miring and cleaning the machine. Also, the invention involves features of construction whereby the top and bottom rolls can be cleaned of any Wool that might stick to them during the process of washing, means for individually adjusting the top rolls and an improved way of supporting the weights for holding them down. The entire set of top rolls can be lifted out of the way to permit stringing up the machine and can then be let down into position without necessitating any adjustment which is an important improvement.

Other features and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a side View of a back washer provided with a preferred embodiment of this invention;

Fig. 2 is a plan of the same; and

Fig. is a side view of the supports for the top and bottom rolls on enlarged scale showing some modifications.

Ordinarily, the top rolls of a back washer of this kind are individually mounted and individually removable. They are also indiviually weighted. This necessitates the taking out of these heavy rolls separately whenever the sliver is to be strung through the machine and also in case of repairs or cleaning. This is a long process consuming considerable time.

In order to avoid this diliiculty, I have provided the back was'l'ier with. pivot rod 1 extending transversely on'wli'ioh is ivoted a fr m 12 having'its ends at opposite sides of the washer. Th'isfram is provided with a series of bearings 13 mountain radial slotsM in thefraine and kid justed by screws 15 individually and radially.

' Thesebearings arry the studs oi' shafts 16 of the top rolls 17. These top rolls therefore are all supported on this frame 12.: They are arranged on the are are circle and although they are individually adjustable, they are collectively removable from the inachine by swinging the f'rameg12 upwardly from the positionsliowii in' l in full lines to that shown in dotted lines. The frame 12 is weighted at both ends by two sets of weights 18 mounted on studs 19 located on the two'end frames. These weights exert their pressure on the whole set of top nin and it is a comparatively simple matter to change them to secure mote or: less weight. I provide the frame 12 with a handle 21 for raising "and lowering it.

I have also shown the set of" bottom rolls 20 mounted in fined hearings and arranged around the arc of a circle concentric with that on which the top rolls are mounted so that each top roll contacts with a bottom roll when the device is in operation and exerts its pressure in a radial direction. I also provide under the bottom rolls a concave perforated bottom plate 22 and above the top rolls a similar shaped perforated top plate 23. For the purpose of cleaning the two sets of rolls from any wool or fiber that may stick to them or wind around them, I provide angular cleaning strips 24 at the top and bottom preferably extending along each roll so that the material will never go around these rolls. I can, if desired, as shown in Fig. 3, form the bottomperforated plate 22 in undulating form to assist in preventing the passage of the material or sliver around the rolls. cleaning strips 24; if desired.

I have also shown the guide rolls 26 usually employed. The rest of the machine is not illustrated but of course it is used with the ordinary main squeeze rolls and feed stand rolls.

This constitutes an immersing mechanism for forcing the stock down below the surface of the liquor, pressing it under considr This can be used Without the' ported by the frame or stand.

erable weight afforded by the weights 18 so as to squeeze the stock and cause its full saturation While feeding it to the main squeeze rolls. The rolls which accomplish this object are suspended by the pivoted swinging frame and they are located in radial position preferably. The adjustable bearings 13 are provided to create the proper contact with the bottom rolls. The bottom rolls are gear driven if desired and located radially inside the back washer, sup- The perforated sheet metal pans 22 or 22 are provided ordinarily as guards to assist in 0011- veying the stock. If the sliver fails to continue to pass between the rolls in the ordi- 1 nary way the pans, especially when formed in the corrugated shape shown in Fig. 3, assist in holding it against the rolls so that it will continue on in its usual path. The strips 24 act either in conjunction with this corrugated pan, or without it, to strip the material off the rolls if it starts to wind around them.

In this way it will be seen that the above mentioned objects are secured and especially that the top rolls can be removed from the washer by a single'operation and kept out of the way while the sliver is being strung through the machine or for any other purpose and then they can be put down again without readjustment and will come into proper contact with the bottom rolls to secure efficient operation. The fact that readjustment of the, individual rolls is not necessary is very important as it saves much time.

Although I have illustrated and described only two forms of the invention, I am aware of the fact that other modifications can be made therein by any person skilled in the art Without departing from the scope thereof as expressed in the claims. Therefore, I do not wish to be otherwise limited to the details herein disclosed but what I do claim 1s:

1. The combination with a backwasher for card and comb tops and the like, of a set of squeeze rolls mounted to rotate on stationary axes comprising top and bottom sets of rolls, and means whereby the entire set of top rolls can be lifted from the bottom rolls and reset in the same fixed relationship against them without adjustment.

2. The combination with a backwasher, of

a set of bottom rolls, a frame pivotally mounted above them, adjustable bearings on the frame and a set of top rolls carried by said bearings and individually adjustable on said frame, whereby when the frame is raised and lowered again, there will be no necessity of readjusting the rolls.

3. The combination with a washing machine, of a set of bottom rolls mounted in. stationary bearings therein in the arc of a circle, a set of top rolls arranged individually adjustable in a radial direction and means for simultaneously lifting all the top rolls about an axis beyond one end of the set of rolls without interfering with their adjustment.

In testimony whereof I have hereunto affixed my signature.

JAMES ALBERT HOGG.
